Tulsa Foundation Co. repairs the full failure chain Green Country clay causes: settlement (piering from $1,200/pier), slab movement (from $3,500), cracks (from $400), drainage (from under $500), and sunken concrete (from $500) — each preceded by a free measured evaluation.
Foundation Piering & Underpinning
Steel piers to refusal, with depth probed and logged per location because it varies across the valley.
Slab Foundation Repair
Perimeter or interior support for slab-on-grade across the suburban ring, guided by the floor survey.
Foundation Crack Repair
Injection, carbon staples and masonry repair on midtown pier-and-beam and partial-basement stock.
Drainage Correction
Sized for rain that arrives all at once rather than steadily — the highest-value line on many Tulsa scopes.
Concrete Leveling
Polyurethane lifting for drives, walks and porch slabs.
Foundation Settlement Repair
The full sequence where a corner has dropped: measure, underpin, then repair what cracked.
Pier & Beam Foundation Repair
Sills, girders and piers under midtown homes on pier-and-beam or partial basements.
Helical Piers vs Push Piers
Helical against push piers, and how the choice changes when depth to refusal varies by neighbourhood.
Exterior vs Interior Waterproofing
Which side to solve the water from when it arrives in quantity rather than steadily.
Insurance & Foundation Repair
What Oklahoma policies typically exclude, and the narrow cases that get paid.
Structural Engineer or Contractor?
When an independent engineer is worth the fee, and when the elevations already answer it.
Cost Guide: What Repairs Run in Tulsa
What actually moves a number here, and why two bids across town can differ honestly.
Why the services come as a set
Expansive clay does not specialise. A drought-to-deluge swing pulls moisture out of the ground and then puts it back all at once, and the same movement that drops a footing cracks the brick above it and tilts the slab outside. One mechanism, several symptoms, routinely sold as several unrelated products.
A company organised around a product sells that product. We are organised around the soil, which is why the evaluation reads the whole chain and the scope carries only the links your house actually needs.
Which repair fixes which failure
| What you see | The clay mechanism | The fix | Typical range | Time |
|---|---|---|---|---|
| Stair-step cracks, dropped corners, sloping floors | Clay pulling away from the footing during a long dry stretch | Piers to stable bearing | $4,000–$15,000 | 2 days–1 week |
| Interior slab cracks, doors racking | Uneven rebound beneath a slab when heavy rain reaches the clay all at once | Perimeter or interior support | $3,500–$12,000 | 2–5 days |
| Cracks widening between seasons | Drought-to-deluge swings working the same joints open and closed | Injection and reinforcement | $400–$1,500 | Hours |
| Water pooling at the wall, soggy beds | Roof and lot water feeding the moisture cycle | Grading, extensions, drains | Under $500–$6,000 | 1–2 days |
| Stepped driveway joints, tilted patio | Flatwork riding the clay with no footing beneath | Polyurethane lifting | $500–$2,500 | Hours |
Two or more symptoms nearly always share one cause. One evaluation, one scope, one mobilization — that's the cost control this soil allows.
Sequence is the service
Anyone can install a pier. The skill is ordering the work so it stays fixed: water managed before steel goes in, structure stabilised before finishes are repaired, cosmetics last and only once movement is provably over.
Drainage carries unusual weight in that order here, because rain arrives in quantity rather than steadily. Getting a large volume away from the foundation quickly does more for a Tulsa house than the same money spent further down the list. Scopes are written in sequence with fixed prices per line, and lines the measurements do not justify are simply not on them.
Service questions
Which service does my house actually need?
The elevations decide. A floor survey shows which run of the foundation moved and by how much, and the scope follows from that rather than from a package.
Do you charge for evaluations?
We don't charge for evaluations. You get the photographs, the crack measurements and the laser floor elevations whether or not we end up quoting the work.
Can one crew handle structure and water together?
One crew can handle structure and water together, and here it usually should. When rain arrives all at once, getting volume away from the foundation quickly does more for the house than the same money spent further down the scope.
